Filed Oct. 10, 1966, Ser. No. 585,371 U.S. Cl. 182113 Int. Cl. A47] 3/02; E04g 1/16, 5/00 1 Claim ABSTRACT OF THE DISCLOSURE This invention pertains to improvements in building construction scaffolding and is particularly directed to a construction scaffold safety railing.

One of the objects of this invention is to provide a safety railing for construction scaffolding which is easily installed and removed after the job is completed.

Still another object of this invention is to provide a protective safety railing structure for a construction scaffolding which is strong and dependable yet is quick to install and remove with a minimum of skill and tools being required.

It is a further object to provide a railing structure for a scaffolding which is completely demountable and requires a minimum of storage and shipping space for efficient handling and transportation from job to job.

It is also an object to provide a portable railing structure for scaffolding which has a minimum of parts and hardware to put it into effective use.

Further features and advantages of this invention will appear from a detailed description of the drawings in which:

FIG. 1 is a perspective view showing the railing of this invention in use with a scaffolding.

FIG. 2 is an enlarged fragmentary front elevation of a railing post structure indicated by the line 2-4 in FIG. 1.

FIG. 3 is an enlarged fragmentary sectional view on the line 3-3 of FIG. 2.

FIG. 4 is a top plan view of the post structure shown in FIG. 2.

As an example of one embodiment of this invention there is shown a construction scaffold railing comprising a series of support posts each comprising a mounting sleeve consisting of a tubular member having a top 11, bottom 12, and integrally formed sides 13 and 14. Adjacent the forward or front end 15 of the sleeve 10 is 3,425,509 Patented Feb. 4, 1969 fixed a vertically disposed post supporting tube 16 projecting above and below the top and bottom of the sleeve 10 and arranged to telescopically receive the railing post 17. A series of vertically spaced diametrically disposed positioning holes 18 are formed in the railing post 17 and arranged to receive a positioning pin 19 which rests on top of the tube 16 to vertically position the railing post in desired position.

A series of vertically spaced pigtail railing cable hooks 20 are fixed on the inner faces of the railing posts 17 and are arranged to releasably secure suitable railing cables 21. The sleeves 10 are slipped over the outer ends of the horizontal joist members 22 of the vertical studding 23 of the building structure and secured thereon by suitable removable double-headed nails 24. Suitable plywood sheets or boards 25 forming the walkway are placed over the tops 11 of the sleeves 10 and the joists 22 to complete the scaffolding with the protective railing as described.

While the apparatus herein disclosed and described constitutes a preferred form of the invention, it is also to be understood that the apparatus is capable of mechanical alteration without departing from the spirit of the invention and that such mechanical arrangement and commercial adaptation as fall within the scope of the appendent claims are intended to be included herein. v

Having thus fully set forth and described this invention what is claimed and desired to be obtained by U. S. Letters Patent is:

1. A construction scaffold safety railing support element comprising in combination:

(A) a mounting sleeve arranged to slip over the outer joist ends of a building being constructed consisting of (C) a bottom,

(D) integrally formed vertical sides,

(E) a vertically disposed post supporting tube fixed in and extending between said top and bottom adjacent an end of said mounting sleeve, and

(F) nailing holes formed in said vertical sides for demountably securing said mounting sleeve on said joist ends.
